cannot boot from MicroSD - "failed to mount mmcblk0" and "cannot load volume /misc"

[Keybitemp]

Hello guys,

 

it's day i'm trying everything to let my S905x TV Box run Armbian but i keep struggle at toothpick multiboot.

Android recovery stays with the green android with the ! out of its tummy and hang with the "Cannot load volume /misc!" error.

I opened the log and find out "failed to mount /dev/block/mmcblk0 on /sdcard by read-only (Device or resource busy)".

 

I downloaded the image and wrote it on a 32GB MicroSD card via Rufus,

 

Could someone please suggest me how to proceed?

Thank you,
Marco

I forgot to told you i'm already using the same TV box with lakka booting the system from another 64gb microSD card.

 

Thanks you!

Read the part about having run *any* other distribution on your box before trying the armbian builds.

As i wrote (and i remember well) i didn't install anything on the box.

Lakka boot from microSD, if i remove It the regular tvbox system will load.

I also tried using the tvbox update application but It doesn't find any file.

The instructions don't say install, they say run.  Running from SD card may/will change the boot environment on the mmc and prevent armbian from booting.  If you have ever *run* another distribution on the box armbian may not run.  You need to reinstall the original android firmware to reset things back to what armbian expects.

Then i'm stuck, i have absolutely no idea how to do It.

Thank you anyway.
